It will be observed that the mechanism re quired is simple, inexpensive and compact, and that space is saved through the mounting of the warp beam below the guide roller 3, without losing the advantage that in all positions of the rwarp beam and with the continually changing diameter pr per tension on the work is maintained at all times H i i I claim as my invention: I
